This is pretty fucking banana sandwich. Very impressive and may even help you understand compsci a bit better.
Here’s an AI generated summary of the video:
In the video “I Made a 32-bit Computer Inside Terraria,” the creator shares their remarkable accomplishment of constructing a fully functional 32-bit computer simulation within the popular game Terraria. They utilized the game’s wiring mechanics to create complex circuits and successfully developed a computer capable of executing instructions and storing data. The video mentions future plans to create a simplified version of Terraria within the game as the next milestone. The project is open-source and can be found on GitHub for further exploration.
But can it play Doom?
It can render 3d environments (very slowly at the moment) and I believe they plan to port Doom to it before porting Terraria to it.
